Worked with Electric Commander migrating a group from their unsupported build environment into the standard Electric Commander based solution. This involved using Cygwin, bash and LSF to farm builds out to a pool of Windows servers to perform builds. Builds were down using Visual Studio 8.0, 9.0 and 10.0. Build system also used Perforce and Perforce trigger to fire builds as the engineers checked in code.
Implemented Perl module, Clearquest::REST, to replace a Clearquest Daemon that was in use so that systems that did not have Clearquest installed (e.g. Linux build machines) could talk to Clearquest to update defects when required. Modified Perforce and Git triggers to use this REST interface.

Managed and executed day to day build and release duties. Served as Clearcase/Clearquest Administrator as well as overall support of systems. Assisted with creating UCM streams and handling of rebase and delivery issues for engineers and the build/release process. Wrote UCM triggers to notify users of deliveries from UCM development streams. Created baselines for official builds. Took over day to day build and release duties. Created a build script that united the various quick and dirty build scripts that were oriented per stream and per build option. This standardized the build process. Augmented this build script to be a daemon that continually builds software when deliveries are detected. Wrote a build status web page that tracks and monitors the continuous building. Created a dynamic web page to show Junit test history. Converted Windows build from bat files and scheduled tasks -> Cygwin and cron thus making the build script identical on both Linux and Windows.

Served as Clearcase/Clearquest Administrator as well as overall support of systems. Developed several triggers as well as ported my mktriggers script which automates the maintenance of triggers.
Developed a complex Perl script to merge two Clearquest databases to a new database with many schema changes. This script handled all aspects of the conversion including changing non US ASCII characters found in the data to their HTML equivalents, dynamic creation of dynamic lists, field renaming and dynamically creating new stateless records as needed.
Developed a script to better handle merging from UCM deliveries and rebases by delaying any non automatic merges to the end of the process as well as handle binary element merge. This process, written in Perl, utilized PerlTk to present the user with a GUI dialog box to choose which version of the binary file to merge.
Designed and developed another Clearquest database for the Mobile Multimedia group.
Wrote several other scripts including one to interface CVS to IMS (a defect tracking system) recording the change set at commit time, a script to strip out MIME/HTML and attachments for defects submitted to GNATS (another defect tracking system). Also implemented several script to log Clearcase activity, check Clearcase's pulse and gather site and vob statistics. These scripts were the start for creation of a set Object Oriented Perl modules to encapsulate Clearcase in a Perl like manner (still in development).
